Jpa 使用Eclipselink创建或扩展表无效

我使用的是Eclipselink 2.5.1，当我运行Project->JPA Tools->Create tables form Entites时，没有发生表更新的问题。。。虽然我有

<property name="eclipselink.ddl-generation" value="create-or-extend-tables" />

尽管我说了创建或扩展表，为什么eclipselink试图删除并重新创建表地址？

“eclipselink.ddl生成”是一个eclipselink运行时属性，当您部署peristence单元时会查看它，但您没有运行/部署持久化单元。相反，您正在执行一个Eclipse命令来从您的实体创建表。Eclipse在封面下使用EclipseLink，但会传递它自己的属性，以确保在它所指向的数据库上创建表。此处介绍了这些设置：

如果你想让EclipseLink扩展你的表格，只需运行你的应用程序。

对@Chris May 15，2014提供的答案有什么想法吗？
